Improvement in supporters for spinning-rings



UNITED STATES THOMAS MARSH, OF NORTH PROVIDENCE, RHODE ISLAND.

IMPROVEMENT IN SUPPORTERS FOR SPINNING-RINGS.

Specification forming part of Letters Patent No. 118,622, dated August29, 1871.

To all whom it may concern:

Be it known that I, THoMAs MARSH, of North Providence, countyofProvidence, State of Rhode Island, have invented certain new anduseful Improvements in Rings and Ring-Supporters for Spinning-Frames, ofwhich the following is a specification The nature of my inventionconsists in making a dovetail or cut-under rabbet in the ring-supportera little smaller than that part of the ring which the supporter holds,so that, as the sup porter has cuts or kerfs in it, the ring may beforced into the rabbet in the supporter, in which case the supportercontracts onto the ring by its own elasticity.

Figure 1 represents a plan of the ring-supporter. Fig. 2 is a section,showing a ring-supporter and the ring itself. Fig. 8 is a plan, showingthe under side of a ring. Fig. 4 is a section, showing the ringinverted.

Lot A represent that part of the spinning-frame to which the rings areattached. B, Figs. 1 and 2, represents a ring-supporter provided with arabbet, c c, on its upper face, as represented in Figs. 1 and 2. Thewall of the rabbet is somewhat out under, as represented at c, Fig. 2,so that it may more securely hold the corresponding number, d, Fig. 4,on the under side of the spinning-ring. The ring-supporter B has a cutor kerf, as shown at D, Fig. 1., to admit its taking the number 61 ofthe ring into its rabbet c c, as represented in Fig. 2. The rabbct c cof the ringsupporter, Fig. 1, is eccentric to the body to admit theadjustment of the center of the ring in relation to the center of theopening of the ringframe A. The ring itself is made as represented inFigs. 3 and 4, being provided with an eccentric number, (1 e, on itslower edge, as represented in Fig. 4. This eccentric number d e fitsinto the rabbet c c of the ring-supporter B, Fig. 2.

By this construction of the kerfed ring-supporter, the eccentric rabbetc c, and the rabbeted ring (J, I am enabled to apply or remove the ringwith very little trouble, and also to adjust the ring with reference tothe spindle by simply turning the ring-supporter or the ring itself, orboth.

I claim as my invention- The cut or kerfed and rabbeted ring-supporterB, when the rabbet is out under or dovetailed, as described, and engagesa corresponding part on the ring which it is intended to hold,substantially as described.

THOMAS MARSH.
